【摘要】 首次提出了变精度二次测量轮廓术，利用这一技术，在相位恢复过程中，对有断点及边界区域也能得到正确的去包裹相位值。文中讨论了相位恢复的误差容限。最后，把这一技术用于三维面形测量中，并得到了较好的实验结果。更多还原

【Abstract】 A new method is presented to acquire 3D profile of an object by measuring theobject twice. This technique can produce a correct unwrapping in the presence ofdiscontinuites in the process of Phase restoring. We introduce it into the measurement of a3D object shape and obtain satistactory experimental results.更多还原
